CentOS - Jul 2011 - CentOS 6 x86_64 DVD doesn't boot

Hi Everyone,

I downloaded the CentOS 6 x86_64 DVD ISOs and burned the first image to
a rewritable DVD.  When I tried to boot my new home server off it, it
didn't, and then this was printed to the screen:

ETCDisolinux: Found something at drive = EF
No DEFAULT or UI configuration directive found!
boot:

The same disc works fine in my 4 year old HP laptop, and when installing
CentOS 6 as a KVM.

I've found one post from a Fedora 14 user that was having the exact same
problem, but no one replied to him.  Other articles, posts etc. around
the net reference something different for the "EF" part.

Does anyone know what's going on? I've never seen this problem before.

Regards,

Ranbir

I had an smililar issue using the CentOS 6 DVD with a DVD-RW.  The same
install disk worked perfectly on another system.  I ended up having to use
the Netinstall CD to do the install.

This is often a side effect of what I have been told is a poor specification
in the DVD industry regarding writing at > 1x speed, in that certain
requirements were set for that speed but not for higher speeds.

I have had much better luck with DVD data portability if I always 
burn DVDs at 1x (or as close to it as the DVD firmware will allow),
particularly when it comes to burning on one system and reading on
another.

By any chance is the drive that does not work *NOT* a CDRW drive? 
Sometimes CD-ROM drives do not like reading rewriteable media.

I've tried everything people have so kindly suggested - the DVD has
failed to boot each and every time.

I decided to burn a Fedora 15 x86_64 DVD ISO to the same rewritable DVD
I've been using for the CentOS 6 DVD image. I also used the same burner.
The Fedora 15 DVD booted just fine.

So, what I can conclude is something is broken.  :/

Brasero and K3B both use growisofs and wodim on the backend.  Burning DVD- is a
different process from burning DVD+; substantially different at the physical
media, and thus different bugs are exposed.

Jorg Schilling's own cdrecord utilities may work more reliably for DVD-
burning (he says they should work better for all burning, but I haven't
tested that).  YMMV.  Jorg is not as gracious about the differences and about
the issue as I am being here; you can read it all for yourself and decide for
yourself what to do about that.... but using his cdrecord suite is guaranteed to
make your system not 100% upstream EL compatible.... at least in terms of those
utilities.

I know a client of mine has had multiple problems with Brasero and certain
brands of media, mostly DVD-, when I haven't had issues, but using DVD+
almost exclusively.  I'm probably going to rip out wodim completely, and try
out Jorg's mkisofs and cdrecord instead, and see if that fixes the problem. 
But I digress.
